Description

Technical Field

[0001] The present invention relates to the field of rainwater and sewage diversion, and in particular to an automatic rainwater and sewage diversion system and diversion method for intelligent buildings. Background Art

[0002] Rainwater and sewage separation refers to a sewage discharge method that separates rainwater and sewage for discharge or subsequent treatment. Rainwater is discharged directly into the river through the rainwater pipe network, and sewage is collected through the sewage pipe network and sent to the sewage treatment plant for treatment, so as to avoid sewage directly entering the river and causing pollution.

[0003] In the prior art, the rainwater and sewage diversion system for buildings usually includes an independent double pipe and a diversion device. The independent double riser means that two risers are used to completely separate rainwater and sewage. The diversion device includes a main pipe, a sewage pipe, a three-way valve, a sewage pipe, a rainwater pipe, a rainfall detection sensor, a water quality detection sensor, etc. The top of the main pipe is connected to the roof of the building, and the sewage pipe is connected to the main pipe and the sewage outlet of the residents (the sewage pipe here is mainly used to discharge the domestic water of the residents, such as laundry, vegetable washing, etc.). The three-way valve connects the main pipe, the sewage pipe and the rainwater pipe. In normal state, the main pipe and the sewage pipe are connected to discharge domestic sewage to the sewage treatment plant. In heavy rain, the main pipe and the rainwater pipe are connected to discharge the rainwater accumulated on the roof.

[0004] With the above two diversion technologies, the cost of independently connecting two main pipes is relatively high, and heavy rain and rainstorm weather are relatively rare. Especially for areas with less rainfall, setting up a single main pipe to discharge rainwater from the roof has a low utilization rate. And with the above diversion device, it is difficult to achieve the diversion and discharge of rainwater and sewage at the main pipe stage at the same time when it rains.

[0005] Therefore, it is necessary to provide an automatic rainwater and sewage diversion system for intelligent buildings to solve the above technical problems. Summary of the invention

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] The invention provides an automatic rainwater and sewage diversion system for intelligent buildings.

[0050] Please refer to Figures 1 to 3 In one embodiment of the present invention, the automatic rainwater and sewage diversion system for intelligent buildings comprises: a main pipe 1, a partition device 2, a diversion box 3, a first valve member 4 and a second valve member 5;

[0051] The main pipe 1 is connected to a plurality of sewage pipes 101 at intervals, and the top of the main pipe 1 passes through the roof 8 of the building and is flush with the top surface of the roof 8;

[0052] The diversion box 3 is connected to the bottom end of the main pipe 1, and rainwater outlet pipes 31 and sewage outlet pipes 32 are respectively arranged on both sides of the diversion box 3;

[0053] The partition device 2 comprises a support block 21, a partition plate 22, a rotating shaft 23 and a rotating device 24, wherein the support block 21 is installed inside the diverter box 3, the rotating shaft 23 is rotatably installed on the support block 21, the partition plate 22 is arranged inside the main pipe 1, the bottom end of the partition plate 22 is fixedly installed on the rotating shaft 23, and the rotating device 24 is used to drive the rotating shaft 23 to rotate;

[0054] The first valve member 4 is used to switch the communication state between the rainwater outlet pipe 31 and the diversion box 3;

[0055] When the main pipe 1 is used to discharge rainwater from the top of the building, the rotating device 24 drives the partition plate 22 to rotate through the rotating shaft 23, thereby separating the main pipe 1 into a rain discharge channel 201 and a sewage discharge channel 202. The second valve member 5 is used to switch the connection state between the rain discharge channel 201 and the sewage outlet pipe 32. The sewage outlet pipe 32 is connected to the sewage discharge channel 202.

[0056] Please refer to Figure 5 By setting the partition device 2, in heavy rainy weather, when it is necessary to drain rainwater from the roof 8, the rotating device 24 rotates the partition plate 22 through the rotating shaft 23, so that both ends of the partition plate 22 abut against the inner wall of the main pipe 1, thereby dividing the main pipe 1 into a rain discharge channel 201 and a sewage discharge channel 202, and the corresponding sewage pipe 101 is connected to the sewage discharge channel 202, and the first valve member 4 and the second valve member 5 work, so that the rainwater outlet pipe 31 is connected to the rain discharge channel 201, and the sewage discharge channel 202 is connected to the sewage outlet pipe 32, and the sewage discharge channel 202 is connected to the sewage outlet pipe 32. 2 is separated from the sewage outlet pipe 32 and is not connected; at this time, the rainwater in the roof 8 is discharged to the river through the rainwater discharge channel 201, the diversion box 3, the rainwater outlet pipe 31 and the laid pipes. In this process, after the user produces domestic water, the sewage flows into the sewage discharge channel 202 through the sewage pipe 101, and then flows into the sewage treatment equipment through the diversion box 3, the sewage outlet pipe 32 and the laid pipes for treatment, so that the sewage will not flow into the river with the rainwater to cause pollution, and at the same time avoid setting up a separate pipe to discharge the rainwater on the roof 8, reducing the cost.

[0057] The partition plate 22 runs through the entire main pipe 1 and has the same length as the main pipe 1. The cross section of the sewage channel 202 is much smaller than the rainwater channel 201. Figure 5 (b) To better meet the needs of rainwater drainage.

[0058] When there is no rain, the assembly state of the partition plate 22 and the main pipe 1 is as follows: Figure 5 (a), the entire main pipe 1 is used to discharge domestic sewage.

[0059] The rainwater outlet pipe 31 is connected to the pre-laid pipeline, and flows into the river etc. through the pre-laid pipeline;

[0060] The sewage outlet pipe 32 is connected to the pre-laid pipeline, and flows into the sewage treatment equipment of the sewage treatment plant through the pre-laid pipeline. After the sewage is treated, it is discharged or reused.

[0061] There are multiple sewage pipes 101, which are connected to the drainage pipes of each household in the building through pipelines, and are mainly used to discharge the household's domestic water, such as water for washing clothes and vegetables.

[0062] A circular hole is formed on the top of the diverter box 3, the bottom of the main pipe 1 is aligned with the circular hole, and a block 21 is installed in the hole wall of the circular hole.

[0063] See also Figure 1 and Figure 2 The automatic rainwater and sewage diversion system for smart buildings also includes a turbidity sensor 9 and a rainfall sensor 10. The turbidity sensor 9 is installed inside the diversion box 3, and the rainfall sensor 10 is installed on the roof 8.

[0064] The rain sensor 10 is provided to detect the rainfall, thereby controlling the states of the first valve member 4 and the second valve member 5 to achieve rain discharge or sewage discharge.

[0065] When rainwater just falls on the roof 8, the dust and other dirt on the surface of the roof 8 mix with the rainwater, causing the early rainwater to become sewage. At this time, this part of the sewage is discharged from the sewage outlet pipe 32. When the turbidity sensor 9 detects that the turbidity of the water flow entering the diversion box 3 reaches a level that can be discharged into the river, the first valve member 4 is opened and the second valve member 5 is closed. At this time, the rainwater can be discharged through the rainwater outlet pipe 31.

[0066] Among them, the automatic rainwater and sewage diversion system for smart buildings also includes a control module, which is used to connect the signals of the turbidity sensor 9, the rainfall sensor 10 and the first valve component 4 and the second valve component 5, and control the working status of the first valve component 4 and the second valve component 5 according to the changes of the detection signals of the sensors, thereby automatically realizing the treatment of rainwater and sewage.

[0067] See also Figure 1 , Figure 2 and Figure 5 As an optional embodiment of the present invention, the partition plate 22 is an arc-shaped plate, and an arc-shaped plate is arranged on the top of the partition plate 22. When the main pipe 1 is only used for sewage discharge, the partition plate 22 fits the inner wall of the main pipe 1.

[0068] By setting the partition plate 22 as an arc-shaped plate, when the inner cavity of the main pipe 1 is not divided, the partition plate 22 can be arranged in close contact with the inner wall of the main pipe 1, thereby reducing the space utilization of the main pipe 1;

[0069] Both ends of the partition plate 22 are preferably provided with sealing sleeves, so that when the two ends of the partition plate 22 abut against the inner wall of the main pipe 1, the sealing can be ensured.

[0070] By setting an arc plate on the top of the partition plate 22, when the partition plate 22 divides the main pipe 1, the arc plate just blocks the top of the sewage channel 202 to prevent rainwater from entering the sewage channel 202 and being discharged through the diversion box 3 and the sewage outlet pipe 32.

[0071] As another optional embodiment, the partition plate may be a square plate, etc., and the arc plate may not be provided. Since the cross-section of the sewage channel 202 is small, only a small amount of rainwater is discharged into the sewage outlet pipe 32, which will not cause a large load on the sewage treatment plant.

[0072] See also Figure 2 and Figure 4 As an optional method of this embodiment, the second valve component 5 includes a second storage box 51, a push cylinder 52, a second valve plate 53 and a connecting plate 54. The second storage box 51 is connected and arranged on one side of the diverter box 3. The second valve plate 53 is arranged inside the second storage box 51. The push cylinder 52 is installed on the diverter box 3. The connecting plate 54 is connected to the output end of the push cylinder 52. The top end of the connecting plate 54 passes through the second storage box 51 through a strip hole and is connected to the second valve plate 53. The second valve plate 53 is provided with an arc portion 531.

[0073] When the second valve member 5 separates the rain discharge channel 201 from the sewage outlet pipe 32, the push cylinder 52 drives the second valve plate 53 to move toward the inside of the diversion box 3 through the connecting plate 54, and the arc portion 531 on the second valve plate 53 is aligned with the dividing plate 22, so that the rain discharge channel 201 can be separated from the sewage outlet pipe 32, and the sewage discharge channel 202 is connected with the sewage outlet pipe 32. When the main pipe 1 is used for sewage discharge, the push cylinder 52 pulls the second valve plate 53 through the connecting plate 54 to move the inside of the second receiving box 51. At this time, the entire main pipe 1 is connected with the sewage pipe 101 and the sewage outlet pipe 32, so as to be used to discharge domestic sewage.

[0074] Furthermore, by providing the arc portion 531 , when blocking, the arc portion 531 is aligned with the partition plate 22 , so that the partition plate 22 and the sewage channel 202 do not have an overlapping portion, and the flow of sewage will not be blocked.

[0075] In this embodiment, the push cylinder 52 is horizontally installed at the bottom of the diverter box 3 through a fixing plate. The push cylinder 52 can be a pneumatic cylinder, a hydraulic cylinder or an electric push rod.

[0076] An extension plate 532 is provided on one side of the second valve plate 53, and the extension plate 532 abuts against the inner wall of the second receiving box 51, so as to prevent sewage from entering the other side of the second valve plate 53 through the second receiving box 51 and being discharged from the rainwater outlet pipe 31 when the second valve plate 53 is blocked.

[0077] As another optional method of this embodiment, the first valve component 4 includes a lifting cylinder, a mounting frame and a sealing plate. The lifting cylinder is vertically mounted on the bottom of the diverter box 3 through the mounting frame. The sealing plate is mounted on the output end of the lifting cylinder, and the bottom of the sealing plate passes through the diverter box 3. An arc portion 531 is correspondingly arranged at the bottom of the sealing plate. When the partition plate 22 separates the inner cavity of the main pipe 1, the arc portion 531 is aligned with the corresponding one, and the lifting cylinder achieves the sealing effect by lifting the sealing plate.

[0078] See also Figure 2 and Figure 5 As an optional method of this embodiment, the first valve component 4 includes a first storage box 41, a first valve plate 42 and a connecting arm 43. The first storage box 41 is connected and arranged on the other side of the diversion box 3. One end of the first valve plate 42 is slidably arranged inside the first storage box 41. The other end of the first valve plate 42 is located inside the diversion box 3 and blocks the rainwater outlet pipe 31. The connecting arm 43 connects the first valve plate 42 and the second valve plate 53.

[0079] When the main pipe 1 needs to drain rain, the push cylinder 52 drives the second valve plate 53 to move to the diversion box 3 through the connecting plate 54 to block the rainwater discharge channel 201 and the sewage outlet pipe 32. When the second valve plate 53 moves, the first valve plate 42 is driven to follow the movement through the connecting arm 43, so that the first valve plate 42 moves to the inside of the first storage box 41. At this time, the rainwater outlet pipe 31 is connected with the rainwater discharge channel 201;

[0080] When only sewage is discharged subsequently, the push cylinder 52 pulls the second valve plate 53 to move into the second storage box 51 again through the connecting plate 54. At the same time, the second valve plate 53 drives the first valve plate 42 to move into the diversion box 3 again through the connecting arm 43 to block the rainwater outlet pipe 31.

[0081] Therefore, the first valve plate 42 and the second valve plate 53 can be driven to open and close by one push cylinder 52, without the need to set up multiple driving devices.

[0082] As another optional mode of this embodiment, the first valve member 4 is a common electric valve or a solenoid valve, which is installed on the rainwater outlet pipe 31 .

[0083] See also Figure 3 and Figure 5 As a preferred embodiment of the present invention, a blocking block 102 is provided on the diversion box 3 and at the bottom of the main pipe 1 .

[0084] By setting the blocking block 102 and setting the support block 21 to be special-shaped, when the second valve plate 53 blocks the rainwater discharge channel 201 and the sewage outlet pipe 32, the blocking block 102 and the support block 21 can block the gap formed between the second valve plate 53 and the partition plate 22 and the hole wall of the circular hole aligned with the main pipe 1, thereby preventing sewage from flowing into the rainwater outlet pipe 31 through the gap.

[0085] See also Figure 3 and Figure 4 The rotating device 24 is a gear, and the rotating device 24 is installed on the rotating shaft 23 . The second valve member 5 further includes a toothed plate 55 , and the toothed plate 55 is installed on a side of the second valve plate 53 facing the rotating device 24 .

[0086] Since the start timing of the partition plate 22 and the first valve member 4 is the same, the rotating device 24 is set as a gear. When the push cylinder 52 pushes the second valve plate 53 toward the inside of the diversion box 3 through the connecting plate 54, and the end of the second valve plate 53 abuts against the inner wall of the diversion box 3, the second valve plate 53 drives the tooth plate 55 to act on the gear on the rotating shaft 23, thereby driving the rotating shaft 23 to rotate, driving the partition plate 22 to rotate, so that when the partition plate 22 rotates, both ends abut against the inner wall of the main pipe 1, and at this time, the end of the second valve plate 53 abuts against the inner wall of the diversion box 3, and the tooth plate 55 is still in meshing with the gear, so that the partition plate 22 can be limited to prevent the partition plate 22 from rotating subsequently. When the main pipe 1 is only used to discharge sewage, the push cylinder 52 pulls the second valve plate 53 back to the second storage box 51 through the connecting plate 54 again. In the process again, the tooth plate 55 acts on the gear again to drive the partition plate 22 to move to the original position.

[0087] Therefore, there is no need to provide an additional driving device for adjusting the state of the partition plate 22 .

[0088] Among them, the rotating shaft 23 passes through the support block 21 and is rotatably connected to the support block 21. The surface of the rotating shaft 23 is provided with an anti-slip cover such as a rubber sleeve to increase the friction with the support block 21, so that the partition plate 22 fits with the inner wall of the main pipe 1 in the retracted state and will not rotate without external force.

[0089] A magnet may also be provided on the partition plate 22, and a metal sheet that can be attracted by the magnet may be correspondingly provided on the main pipe 1, so as to limit the position thereof by magnetic attraction.

[0090] As another optional mode of this embodiment, the rotating device 24 is a motor, which is installed on the roof 8 through a fixing frame, and the output shaft of the motor is connected to the top of the partition plate 22, and the output shaft of the motor is concentrically arranged with the rotating shaft 23.

[0091] See also Figure 6The automatic rainwater and sewage diversion system for intelligent buildings further comprises a cleaning component 6 and a grid plate 11, wherein the grid plate 11 is installed on the roof 8 and is located above the main pipe 1;

[0092] The number of the support blocks 21 and the number of the rotating shafts 23 are both two, the two rotating shafts 23 are correspondingly arranged at the top and bottom of the main pipe 1, the two support blocks 21 are respectively arranged on the diversion box 3 and the roof 8, and the two rotating shafts 23 are correspondingly rotatably mounted on the two support blocks 21;

[0093] The cleaning assembly 6 includes a sliding arm 61, a cleaning frame 62, a swing plate 63 and a convex shaft 64. The cleaning frame 62 is slidably set on the roof 8 through the sliding arm 61 and is located on one side of the grid plate 11. The rotating shaft 23 located at the top of the main pipe 1 passes through the grid plate 11 and is connected to one end of the swing plate 63. The convex shaft 64 is installed at the other end of the swing plate 63, and the top end of the convex shaft 64 passes through the cleaning frame 62.

[0094] The grid plate 11 can be provided to prevent rainwater from driving larger debris on the roof 8 into the main pipe 1 and clogging the main pipe 1 , such as plastic bags and bottles on the roof 8 .

[0095] By providing the cleaning assembly 6, it is possible to prevent the rain from driving larger impurities onto the grid plate 11 during heavy rain.

[0096] When heavy rain occurs, the sewage mixed with rainwater and sludge is discharged first. After the mixed sewage is discharged, when the relatively clean rainwater is discharged, the first valve member 4 and the second valve member 5 are activated to separate the inner cavity of the main pipe 1 into a rainwater discharge channel 201 and a sewage channel, and the rainwater discharge channel 201 is connected to the rainwater outlet pipe 31, and the sewage channel is connected to the sewage outlet pipe 32, and the rainwater discharge channel 201 is separated from the sewage outlet pipe 32. Since the sewage is discharged at this time, the large impurities on the roof 8 are attached to the grid plate 11 at this time, so the cleaning component 6 can be started at this time;

[0097] Please refer to Figure 7 During the rotation of the partition plate 22, the rotating shaft 23 located at the upper end of the partition plate 22 rotates with the partition plate 22, and at the same time drives the swing plate 63 to rotate. The swing plate 63 drives the convex shaft 64 to slide along the cleaning frame 62. At the same time, the convex shaft 64 pushes the side wall of the cleaning frame 62, driving the cleaning frame 62 to move from one side of the grid plate 11 to the other side, cleaning large impurities attached to the grid plate 11 to avoid clogging the grid plate 11.

[0098] Therefore, the push cylinder 52 is used to drive the second valve plate 53 to adjust the opening and closing state of the second valve member 5, and at the same time, the state of the partition plate 22 can be adjusted and the cleaning component 6 can be driven to work.

[0099] See also Figure 6 Preferably, a cleaning sheet 621 is provided at the bottom of the cleaning frame 62, the bottom of the cleaning sheet 621 is flush with the top of the grid plate 11, and the cleaning sheet 621 is provided in two pieces, wherein the cleaning sheet 621 having an overlapping portion with the rotating shaft 23 is deformable, and the cleaning sheet 621 can be deformed when acting with the rotating shaft 23 and the swing plate 63, thereby preventing the cleaning frame 62 from being blocked by the rotating shaft 23 when cleaning the grid plate 11.

[0100] The deformable cleaning sheet 621 can be made of rubber material, leather material, or deformable plastic material, etc. The other cleaning sheet 621 is made of non-deformable material.

[0101] The rotating shaft 23 located at the top of the main pipe 1 penetrates the grid plate 11 through the strip opening on the grid plate 11 .

[0102] Please refer again Figure 6 The automatic rainwater and sewage diversion system for intelligent buildings also includes a baffle 7, which is installed on the roof 8 and located on one side of the grid 11.

[0103] The baffle plate 7 is a U-shaped plate, and its opening faces the grid plate 11 .

[0104] By providing the baffle 7, when the cleaning frame 62 cleans the impurities and moves toward the baffle 7 and moves the impurities out of the grid 11, the cleaning frame 62 limits the impurities between the cleaning frame 62 and the baffle 7 to prevent the impurities from flowing toward the grid 11 again with the rainwater.

[0105] The invention also provides an automatic rainwater and sewage diversion method for intelligent buildings.

[0106] The automatic rainwater and sewage diversion method for intelligent buildings comprises the following steps:

[0107] S1: When the rainwater and sewage automatic diversion system for smart buildings is in the sewage discharge state, the first valve member 4 blocks the rainwater outlet pipe 31, the main pipe 1, the diversion box 3 and the sewage outlet pipe 32 are connected in sequence, and the sewage flows into the sewage treatment equipment through the sewage pipe 101, the main pipe 1, the sewage outlet pipe 32 and the pipeline in sequence;

[0108] S2: When the automatic rainwater and sewage diversion system for intelligent buildings is in the rainwater discharge state:

[0109] Specifically, it includes: S21: the first valve member 4 blocks the rainwater outlet pipe 31, and the main pipe 1, the diversion box 3 and the sewage outlet pipe 32 are connected in sequence, and the sewage mixed with the rainwater and the dirt on the roof 8 is first discharged;

[0110] S22: the first valve component 4, the second valve component 5 and the dividing device 2 work, the dividing device 2 divides the inner cavity of the main pipe 1 into a sewage discharge channel 202 and a rain discharge channel 201, the second valve component 5 works to disconnect the rain discharge channel 201 from the sewage outlet pipe 32, and at the same time the sewage discharge channel 202 is connected to the sewage outlet pipe 32, and the first valve component 4 works to connect the rain discharge channel 201 to the rainwater outlet pipe 31.

[0111] Specifically, when the second valve member 5 separates the rain discharge channel 201 from the sewage outlet pipe 32, the push cylinder 52 drives the second valve plate 53 to move toward the inside of the diversion box 3 through the connecting plate 54, and the arc portion 531 on the second valve plate 53 is aligned with the dividing plate 22, so that the rain discharge channel 201 can be separated from the sewage outlet pipe 32, and the sewage discharge channel 202 is connected with the sewage outlet pipe 32. When the second valve plate 53 moves, the first valve plate 42 is driven to move with it through the connecting arm 43, so that the first valve plate 42 moves to the inside of the first receiving box 41, and at this time, the rainwater outlet pipe 31 is connected with the rain discharge channel 201;

[0112] At the same time, the second valve plate 53 drives the tooth plate 55 to interact with the gear on the rotating shaft 23, thereby driving the rotating shaft 23 to rotate, and driving the partition plate 22 to rotate, so that when the partition plate 22 rotates, both ends abut against the inner wall of the main pipe 1, and at this time, the end of the second valve plate 53 abuts against the inner wall of the diversion box 3, and at this time the tooth plate 55 is still in a meshing state with the gear, so that the partition plate 22 can be limited to prevent the partition plate 22 from rotating subsequently.

[0113] During the rotation of the partition plate 22, the rotating shaft 23 located at the upper end of the partition plate 22 rotates with the partition plate 22, and at the same time drives the swing plate 63 to rotate. The swing plate 63 drives the convex shaft 64 to slide along the cleaning frame 62. At the same time, the convex shaft 64 pushes the side wall of the cleaning frame 62, driving the cleaning frame 62 to move from one side of the grid plate 11 to the other side, cleaning large impurities attached to the grid plate 11 to avoid clogging the grid plate 11.

[0114] Therefore, the push cylinder 52 is used to drive the second valve plate 53 to adjust the opening and closing state of the second valve member 5, and at the same time, the state of the partition plate 22 can be adjusted and the cleaning component 6 can be driven to work.

[0115] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
